What Are the Risks at the Site?
In August, 2016, DOE submitted the most recent Five-Year Review for BNL. This document is used to determine whether the remedies of contaminated sites at BNL remain protective of human health and the environment and to evaluate the implementation and performance of the remedies. At present, soil cleanup levels have been met and the groundwater remediation systems continue to meet the remedial action objectives identified in the RODS. One area of the Peconic River was identified as having elevated mercury levels in sediment, but all other areas have met their long-term cleanup objectives. Some remediation is ongoing, including the HFBR remedy; the long-term protectiveness of the entire site will be evaluated after this and other actions are complete.
BNL is currently investigating contamination by perfluoroalkylated substances (PFAS) and 1,4-dioxane at the base and in the base's vicinity.
EPA uses performance measures to track environmental results at Superfund sites. If you have any questions or concerns about the measures at this site, please contact the site team members listed under Site Contacts.

|Status at this
|What does this mean?|
|Human Exposure Under Control||Yes||Yes means assessments indicate that across the entire site:
No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
|Groundwater Migration Under Control||No||
Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.
No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.
Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.
Yes means the physical construction of the cleanup is complete for the entire site.
No means either physical construction is not complete or actions are still needed to address contamination.
|Sitewide Ready for Anticipated Use||No||Yes means:
No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
